Jpeg Quality

does anyone ever worry about jpeg quality? i am an amatuers amatuer. i use picasa for a lot of photo editing; also use gimp and studio line. in picasa's properties box it gives a jpeg quality number. anyone ever worry about that or know about it?

when taking pictures i often use the histogram feature, and, if the histogram looks balanced, i figure i will have a decent shot. should i worry about jpeg quality or move beyond it. my wife, who doesn't know a camera from a pair of glasses, tells me that if i like the picture i shouldn't worry about the jpeg quality. comments please...........

I have found that if you save jpegs at high quality, the image quality is near perfect, and it's very hard to see any compression at all. However, you don't want to do this multiple times (save over and over again) because then you will get compression artifacts.
Anther option is to save as tif with lossless LZW compression. I design trade show graphics, and the design files and images can get HUGE. I use LZW compression on the images which makes the file much smaller, but the printed output on the trade show booths remains perfect. You can't tell the image was compressed.
